  • Implementation method, system and device of IMS interception
    Patent number: 8320363
    Abstract: The embodiment of the present invention discloses an implementation method of IMS interception, a system and a device thereof. The method includes allocating media anchor points to communication parties; and copying communication content to complete interception of the communication content when the communication parties communicate through the media anchor points. In the present invention, the interception of the communication content can be implemented on the media anchor points instead of the existing media access equipment, thus implementing centralized interception of a media on an IMS network, and ensuring that users accessing the IMS network in various modes can implement the centralized interception of the media on an IMS core without requirement for access side equipment or an extended private interface between the IMS core and the access side equipment.
